Proteomic profiling of vetiver grass (Chrysopogon zizanioides) under 2,4,6-trinitrotoluene (TNT) stress.

ABSTRACT: Vetiver grass is an ideal plant for 2,4,6-trinitrotoluene (TNT) phytoremediation, due to its ability to tolerate and metabolize TNT as previously reported. The current study is the first attempt to investigate the changes in the proteomic profile of a plant under TNT stress. Vetiver plants were grown in nutrient media with varying concentrations of TNT (0, 25, 50, and 100 mg L^-1) for 10 days. Although the plants appeared healthy, significant biomass reductions (p = 0.0008) were observed in treated plants. Total proteins in the root decreased significantly (p = 0.0003). Proteomic analysis of root proteins revealed the downregulation of functional proteins involved in key cellular mechanisms such as transcription, ribosome biogenesis, nucleo-cytoplasmic transport of
